Abstract

A sensor and/or sound detection device having a sensing device having a sensitive surface, an access channel being designed in such a way that air and/or a gas is transferable through the open access channel between a spatial surroundings of the sensor/detection device and the sensitive surface, and an at least partially water-impermeable membrane having respectively an inner side of the membrane facing the associated access channel being designed in such a way that a contact surface on the respective inner side of the respective membrane is pressed against an associated membrane contact surface on the associated access channel in such a way that the associated access channel is sealed in a liquid-tight manner when an outer side of the respective membrane or a covering layer on the respective outer side of the membrane is wetted with at least a minimum quantity of liquid and the respective membrane is deformed.
